ETHAN I. DODDS, OF PULLMAN, ILLINOIS, ASSIGNOR TO THE PULLMAN COMPANY,OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CAR-STAKE.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed July 31,1905. Serial No. 272,052.

To aZZ whom it may concern:

Be it known that I, ETHAN I. DoDDs, a citizen of the United States,residing at Pullman, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Stakes, of which thefollowing is a specification.

The proportioning of the parts of a car stake so as to use the leastamount of metal and yet at the same timeproduce a stake which will mosteffectually withstand the strains put upon it involves particularity anddiscrimination in the distribution of the metal. Since the strains onthe stake are the greatest near its lower part at or near the level ofthe upper surface of the side sill and decrease toward each end, themetal of the stake and its ribs should be proportioned accordingly.

My present invention relates to such stakes, and comprises a base-platewhich is fastened to the sill and to the side or end of the car.Outstanding from this base-plate are two longitudinal ribs, eachtapering toward the base as it approaches the ends thereof, and in oneform of this device these ribs also converge. Uniting these ribs attheir widest partthat is, at the point where they are subjected to thegreatest strain-are one or more transverse webs and an integralconnecting outer portion or back, which joins the outer edges of theribs or webs.

In the accompanying drawings I have illustrated two forms of stakesinvolving my invention.

Figure 1 is the face view of one form of the stake. Fig. 2 is an edgeview thereof. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig.4 is a cross-section on the line 4 4 of Fig. 2, and Fig. 5 is a faceview of a modified form of stake.

1O designates a rectangular base-plate which has holes 11 along itsedges, so that it may be secured to the sill and to the side or end ofthe car. Base 10 is provided also with the outstanding longitudinal ribs12 12, which are widest near the lower portion, approximately on theline i 4, and taper toward the base as they approach the opposite endsthereof. Near their widest portions they are joined together bytransverse webs 14 14 and also an outer rounded integral connectingportion or back 13,Which also joins the outer edges of the transversewebs. It will be seen from this construction that I have devised amately the top of the side sill when it is fastened thereto by bolts orotherwise.

The stake shown in Fig. 5 is provided with a base 10, holes 11 along itsedges, longitudinal ribs 12, together with transverse webs 14, and therounded back 13, all of which are like the parts shown in Fig. 1, withthe exception that the ribs 12 instead of being parallel for theirentire length converge upwardly from their widest portion until theymeet at the upper end of the stake.

From the foregoing it will be seen that in my invention I have produceda cast-metal car-stake which has the advantages of great strength andcomparatively light weight, yet is sufficiently strong for its purpose,because its metal is so distributed as to eifectively withstand thestrains to which it is subjected. Such a cast-metal stake combines amaximum of strength with a minimum of metal and weight and obviously hasadvantageous features other than those specified.

This patent is intended to embrace only so much of the disclosures madeherein as is covered by the claims.

I claim- 1. A car-stake having a base-plate, integral longitudinal ribs,and an integral connecting portion uniting the outer edges of the ribsfor a portion of their length, substantially as described.

2. A car-stake having a base-plate with integral longitudinal ribs, anda rounded integral connecting portion uniting the outer edges of theribs for a portion of their length, substantially as described.

3. A car-stake having a base-plate with integral longitudinal ribstapering toward the base as they approach the ends thereof, and anintegral connecting portion uniting the outer edges of said ribs attheir widest parts, substantially as described.

4. A car-stake having a base-plate with integral longitudinal ribstapering toward the base as they approach the ends thereof, one or morewebs uniting the ribs near their widest parts, and a connecting portionuniting' the outer edges of the ribs and the web or webs, substantiallyas described.

5. A car-stake having a base-plate with integral longitudinal ribs whichconverge as they extend toward the upper end of the base, and aconnecting "portion uniting the outer edges of said ribs for a portionof their length, substantially as described.

6. A oar-stake having a base-plate with integral longitudinal ribs whichconverge as they extend toward the upper end of the base, one or moretransverse webs joining said longitudinal ribs, and an integralconnecting portion uniting the outer edges of said longitudinal ribs andtransverse web or webs, substantially as described.

7. A car-stake having a base-plate with integral longitudinal ribs whichconverge as they extend toward the upper end' of the base, andwhichtaper toward the base as they extend toward the ends thereof,substantially as described.

8. A car-stake having a base-plate with integral longitudinal ribs whichconverge as they extend toward the upper end of the base, and whichtaper toward the base as they approach the ends thereof, and an integralconnecting portion uniting the outer edges of said ribs for a portion oftheir length,

substantially as described.

9. A car-stake having a base-plate with integral longitudinal ribs whichconverge as they extend toward the upper end of the base, and whichtaper toward the base as they approach the ends thereof, one or moretransverse webs uniting said longitudinal ribs near their widestportions, and an integral connecting portion uniting the outer edges ofsaid longitudinal ribs and transverse Web or webs, substantially asdescribed.

In testimony that I claim the foregoing as my invention I have hereuntosubscribed my name in the presence of two witnesses.

ETHAN I. DODDS.
